Application filed October 18, 1966. Serial No. 283.333.

To (ZZZ whom, it may concern} I Be it known that I, FnEDnIoK EBNER, a citizen of the United States, residing at La Crosse, in the county of La (Jrosse and State of Wisconsin, have invented certainnew and useful Improvements in Street-Cleaning Machines; and I do hereby declare the following to .he a full, clear, and exact description of the i invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to street-sweepingmachmes of'the' class adapted to elevate the dirt and dust collected by the sweeper of the .work of the said machine at all.-

To this end my invention consists in the construction and combination of parts hereinafter more particularly set forth and claimed. 4

In the accompanying drawings, Figure 1 represents a perspective view of a machine embodying my invention. Fig. 2 represents a side elevation of the same. Fig. 3 represents a vertical longitudinal section of the same,and Fig. 4 represents adetail plan view ofthe spring-held gearing and proximate parts.

- 1 designates the main section or frame of my sweepingmachine, which carries the r0- tary brush or sweeper A, the endless elevating sheet or apron B, the lateral horizontal discharging sheet or apron C,- the drivingshaft D, and driving-wheels D and D", together with their operative connections and adjusting devices.

2 designates he front truck of my machine, which is provided with a platform N, carrying a seat 0, and a rack 1', upon which an operating-lever N is mounted. The forward part of said truck is supported on an axle P of bearingavheels P P and provided with any suitable means of draft attachment R.

()n the right-hand end of shaft D, against the outer side of driving-wheel D, is loosely mounted the pulley-wheel D which operates the pulle A on the right end of axle A of sweeper by means of the endless driving-beltA On the left end of said drivingshaft and on the outside of drive-Wheel D? 1s fixed the pulley D. This pulleyis connected frame H of the said section 1 of the machine. I

to the. pulley b, which is fast on the left-hand end of the upper roller B of the elevatingsheet B, by the crossed driving belt B, which transmits motion from the former pulley to the latter, rotating the said roller B in a direction'opposite to the direction of rotation of main driving-shaft D. I Splined on the said main driving s'haft D, at some point between the two driving-wheels, is acrown-wheel D engaging the lantern-wheel or pinion E, mounted on the forward end of secondary driving-shaft E, which runs backward from the main driving-shaft. This gear-wheeljD is adapted to slide along the shaft D into and out of engagement with the pinion E aforesaid, but is normally held in such enga ement by the spiral spring X on said shaft l), abutting at one end against wheel D and at the other against the stop 00, which is ri idly mounted on shaft D inside of drive wheel D The discharging sheet or apron C is mounted ori two rollers 0 C held in the opposite ends of a frame C Roller 'C in the ri hthand end of said frame is non-adjustable; ut roller C at the other end of said-frame is adjustable longitudinally thereof b means of the rods 0, adjusting-nuts c, an collars c fixed about the ends of said-roller C By means of this longitudinal adjustment of rollerO the tension of the sheet 0 isregu-b lated. On the forward end of the axle of said roller 0 is a pulley-wheel F, connected to the pulley E on the rear end of shaft E by the driving-belt F. The said shaft E is rotatably mountcd'in a cross-piece H of the The elevating-apron B is held at its lower end by roller B mounted infixed bearings'b in the lower or forward. ends of the side pieces H II of said frame H. The roller B at the TOO lars on the ends of said roller. The said nuts bear against the outsideor rear side of the end piece ll of frame H, so that by turning them the tension on the elevatin -apron may be increased or decreased at wil The upper or rear end of frame H is covered by an arched hood G, extending from the crosspiece H connecting the top edges of the side pieces H 1-1 to. the rear end of the frame which supports the dischargin -sheet and supporting said rear side of said ischargin'gsheet frame. It passes under the said: end

I is so transferred to the upper or rear roller of piece ll of frame H, and the rods 5 work through hole the The lower or forward end of frame H is rovided with a receiving-pan l1, carrying iearings I, in which the ends of axle A of g sweeper A are rotatably i'nounted. ".llie said bearings are braced against longitudinal 5 strain by brace-rods. 1 running from the l upper ends thereof to the side pieces ll? H l l l l The operatingdever N is pivotally mounted on an arm n? of rack N and may bb locked to said rack in any angle of inclination at will by means of the hand-lever n, pivoted on the said operating-lever near the upper end thereof, the spring-catch 11- adapted to normally engage said rack and the connectin red a transmitting motion from said iian lever to said catch in order to disengage it i from the said rack. The rear or lower end of said operating-lever N is connected to the suspending-rod B the ends of which are secured to the sides of the frame ll. The sup ports N of platform N are rearwardly 'n'oduced beyond the driving-shaft D, which passes through them, connecting the two sect-ions 1 and 2 ofthe machine together.

The general o eration of my invention is as follows: The handle of operating-lever is raised upward and backward, lomering the sweeper A into. operative contact with the surface to be swept. The pulley D turns with. driving-wheel D, and its motion is transmitted by the endless belt A to the pulley A on the axle of the sweeper, causing said sweeper to revolve in the same direction, brushing all refuse in its path into the receiving-pan and thence onto the elevatingsheet B. The pulley I) on the left end of shaft D turns with said shaft, and its motion said elevating-sheet by means of the crossed endless belt, that said roller rotates in a direction opposite to that of the main shaft and causes the sheet B to travel over it from front to rear of section 1 and carrying all refuse cl'uirge-sheet C. The shaft E, receiving ruotion from the main driving-shaft D, transmite the same to end roller 0" of dismal-gesheet C by means of endless belt F.- This causes the rotation of roller C toward the rigid, drawing upon the disehargingsheet C in the same direction and cansinv it to travel in its frame, so as to carry all refuse dumped upon it by sheet B out to the roller 0 in the right end of said frame (i from which it drops into a wagon or other receptacle not a part of said invention.

The spring X keeps pinion D in mesh with gear-wheel E without risk of separation or strain while the machine is turning curves. The pulley D carries a pawl Z, engaging a ratchet-wheel Z, carried by wheel D, these parts being arrangedto drive the said pulley, the belt 1 and the brush A while t e machine goes forward and to ermit the said pawl to ride freely over thelli ing ralehet wheel when. the machine is backed. Thus the latter movement will not turn the sweeper or brush A.

Having thus described. my invention, what I claim as new, and desire to secure l y Letters Patent, isv In a street-sweeping machine, a rotary brush in combination with the main jf'iKlS- porting-wheels and their axle, a bowl gearwheel sliding on said axle, a sprin pressing on said gear-wheel, a lantern-whee meshing with said bevel gear-wheel, a shaftturning with said lantern-wheel, an endless conveyer driven by said shaft, another endless conveyer, gearing from the shaft of said brush to drive the same and a pawl and flat-Chet operating w th this gearing to prevei backward moti i :1 substantially as set foryh.

In testi; iOIlY whereof i have signed my .name to this specification in the presence of two subscribing witnesses. h
